IMPROVEMENT IN WAGON-AXLES.

Specification forming part of Letters Patent No. 205,591, dated July2,1878; application filed October 4, 1877.

To all whom it may concern:

Be it known that I, PATRICK R. WALSH, of Vallejo, county of Solano, andState of California, have invented an Improvement in Wagon-Axles; and Ido hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawings.

My invention relates to that class of wagon or carriages axlesconstructed in such a manner that the spindle ends can be taken 0d andreplaced without disturbing the axle in its bed; and it consists inproviding the removable spindle with an extension-piece, so that a clipcan be put between thejoint and the spindle proper, which givesadditional strength, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view. Fig. 2 isa longitudinal section.

Let A represent a wagon or carriage axle, and B the spindle, or thatportion outside the axlebed on which the wheel turns. This spindle endis constructed with an extensionpiece, E, so that it can be taken offfrom the main part of the axle at a point, 0, inside the inner end ofthe spindle B a sufficient distance irom the collar a to allow theintroduction of a'elipbetween the joint and the spindle. This joint orconnection is made by a projecting screw, D, on the inner end of thespindle, which fits into a thread cut in the end of the axle A. Thescrew D is made to taper from the end, as shown, so as to be of nearlyuniform strengtlnand overcome the liability of breaking at the base ofthe screw.

The axle A is secured to the axle-bed by clips in the usual manner, andthe joint 0 is made at a sufficient distance from the shoulder at theinner end of the spindle to allow a clip to be used to secure thisportion, and thus prevent any separation of the joint, and to se cure itfirmly to the axle-bed.

An axle formed in one piece, if broken, necessitates its entire removalfrom the axlebed and carriage, in order to be repaire l, causing anexpenditure of time and labor, and injuring the appearance of thecarriage, paint and varnish necessarily being marred and scratched inthe operation; but by my inven tion, in case of a break, which almostuniversally occurs at the inner end of the spindle, the axle is takenapart at the joint C, a new spindle end, B, fitted to the axle Withoutremoving it from the axle-bed or the carriage in any Way, thusovercoming the difficulties and objection of repairing a broken axleconstructed of one piece in the ordinary manner.

Axles constructed in this manner may be kept in stock of standard sizes,and when one is broken it will only be necessary to replace the brokenpart at a small expense.

I am aware that removable spindles attached by screws have heretoforebeen used, and hence I do not claim such arrangement broadly; but,

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The removable spindle B, provided with an extension-piece, E, and screwD, in combination with the axle A, provided with a female screw, as setforth.

In witness whereof I'have hereunto set my hand and seal.
